I am experiencing an extremely strong mildew smell inside my equinox. It is so strong people comment outside the car. The smell also penetrates clothing so that others notice the smell. People will not ride in my car. I have had it to the dealer twice. Both times the odor improves slightly (they depdorize the HVAC) but still others comment.

What stands out
No new NHTSA body complaint has been filed on this vehicle in over 19 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Water leaks into the floor and spare tire area are the dominant defect in 2005 Equinoxes, causing mold and mildew; GM has acknowledged the factory sealing problem but won't cover repairs out of warranty. Additional issues include rear hatch strut failure, door latch failure, and front subframe corrosion.
Water intrusion is the primary problem. Owners consistently report water pooling in the spare tire compartment, front and rear floorboards, and accumulating in areas under the cargo area. The culprit is a seam under the luggage rack that wasn't properly welded at the factory—water runs down the D-pillar and collects inside. One owner found almost two feet of standing water after heavy rain. Water dripping from overhead lights when braking suggests a design flaw in drainage paths. Black mold and mildew smell develop quickly in saturated carpet padding and are persistent; some owners report the smell lingers even after dealer deodorizing attempts. GM has a technical bulletin (2198426) acknowledging improper factory sealing, but the company refuses to cover repairs on vehicles out of warranty. A dealership's attempt to fix the problem by replacing the windshield failed.
Rear hatch strut failure is the second major issue. The hydraulic lift supports quit without warning, leaving owners unable to open the heavy hatch safely. When struts fail, the hatch slams down with force—a serious injury hazard. One owner reported a tailgate support rod detaching entirely and striking their hand.
Minor but notable: doors opening while driving, glove box latches breaking, and front subframe corrosion causing clunking.

Failure modes owners describe
Water intrusion through improperly welded seams and factory sealing defects
Water leaks into the vehicle interior through structural seams, particularly a seam under the luggage rack that was not properly welded at the factory. Water accumulates in the spare tire compartment, front and rear floorboards, and the D-pillar area. Owners report standing water, saturated carpet padding, and water dripping from overhead lights when braking. GM bulletin 2198426 acknowledges the vehicle was not sealed properly at the factory.
When: Complaint #1: October 2009, after accumulated rainfall over 10 inches. Complaint #3: water drips from overhead lights when braking. Complaint #7: every time it rained, 1-2 inches of water in floorboard. Complaint #10: presented around 50,000 mile range.
Symptoms owners cite: Standing water in front driver/passenger and rear passenger floorboards; Water in spare tire compartment accumulating several gallons; Saturated carpet padding between body and tire; Water dripping from overhead lights when braking; Musty, mildew, and black mold odor inside vehicle; Black mold visible in affected areas; Staining and odor in interior carpet
Repairs/costs cited: Complaint #1: seam under luggage rack needs to be welded properly and carpet completely replaced. Dealership diagnosed seam under luggage rack was not properly welded. Complaint #7: dealer replaced windshield but problem continued.
Recalls/TSBs owners mention: GM bulletin 2198426 acknowledges improper factory sealing; GM refuses to fix under warranty citing vehicle is out of warranty; dealerships will not fix at manufacturer cost; some owners report windshield replacement attempted but ineffective.
Rear hatch hydraulic strut failure
The hydraulic pumps (lift supports/struts) that hold the rear hatch open stopped working suddenly without warning. The hatch becomes impossible to open safely because it is too heavy to lift manually and will slam down with force if the struts fail.
When: Complaint #4: failure sudden with no warning. Complaint #9: liftgate support rod detached while in up position.
Symptoms owners cite: Hydraulic pumps quit working without warning; Hatch too heavy to lift manually; Hatch slams down very hard when strut fails; Rear hatch cannot be opened safely; Liftgate support rod detached while in up position
Repairs/costs cited: Complaint #4: owner looking into buying replacement strut pumps (Stabilus USA, model 4992RQ0830N 007105 B20). Complaint #8: owner states this type of failure never happened in previous GM lift-back vehicles. Complaint #17: tailgate collapsed due to left strut not providing enough lift; tailgate came down rapidly on owner's hand.
Door latch failure causing spontaneous door opening while driving
Driver's door opened independently while vehicle was in motion at various speeds without the driver operating the latch. Failure recurred multiple times, rendering the vehicle unsafe.
When: Complaint #11: at approximately 78,000 miles while driving approximately 30 mph.
Symptoms owners cite: Door opened independently without warning while driving; Failure recurred multiple times; Vehicle unsafe to operate
Recalls/TSBs owners mention: Manufacturer was not notified; vehicle was not diagnosed or repaired.
Glove box latch bracket failure
Glove box striker bracket broke off at the bolt attachment points, causing the glove box to pop open during driving and spill contents.
When: Complaint #15: while driving to the store.
Symptoms owners cite: Glove box popped open while driving; Contents spilled out; Striker bracket broke off at bolt attachment points
Repairs/costs cited: Striker bracket broke at point where it attaches to bolts.
Front subframe corrosion and detachment
Front uni-body to front engine/transmission subframe mounting area rusted away, causing the front subframe mounting points to separate from the uni-body structure due to corrosion.
When: Complaint #13: timing not specified.
Symptoms owners cite: Front subframe mounting points corroded away; Subframe no longer connected to uni-body due to rust; Clunking noise while driving
Repairs/costs cited: Left front and right front subframe mounting points corroded.
Rear window air buffeting
With rear windows down at various speeds, air thumps and pounds through the vehicle causing ear discomfort. Dealership and manufacturer determined this is how the vehicle was designed.
When: Complaint #12: update dated 5/2/2006.
Symptoms owners cite: Air thumps and pounds through vehicle with rear windows down; Discomfort to ears
Recalls/TSBs owners mention: Dealership and manufacturer stated this is how the vehicle was manufactured.
Cup holder blocking emergency brake lever
Cup holder is positioned to block or interfere with the emergency brake lever, preventing proper operation or access.
When: Complaint #18: timing not specified.
Symptoms owners cite: Cup holder blocks emergency brake
Console and hood excessive heat generation
Console and hood produce extreme heat, raising fire risk concerns in the owner's mind. Cause not determined.
When: Complaint #14: timing not specified.

Common questions
How serious is the body problem on the 2005 Chevrolet Equinox?
It's a meaningful issue. 19 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $1,500.
At what mileage does the body typically fail?
Across the 11 complaints that reported odometer mileage, most body failures cluster between 9,500 and 78,000 miles, with the median around 50,000. A quarter of owners report trouble before 9,500; a quarter make it past 78,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $1,500 for body repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to body?
No active recalls currently cover body issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
